RESUMO
UNLABELLED: Changes of lipid metabolism are often observed in patients (pts) with chronic viral hepatitis during interferon therapy. Many studies show changes in blood lipids including increase of triglycerides level, decrease of total cholesterol as well as HDL lipoprotein levels. This study was an attempt to widen our knowledge about additional factors responsible for changes in lipid metabolism of pts with chronic viral hepatitis during interferon therapy. The aim of this study was to assess the changes of total cholesterol, triglycerides and LDL-, HDL-lipoproteins levels in blood serum in comparison to: activity of hepatic inflammation, degrees of fibrosis, type of hepatotropic viruses and response to antiviral treatment. MATERIAL AND METHODS: In the group of 53 pts (18 female, 35 male), age 16-61 years old with chronic hepatitis B (13 pts) and chronic hepatitis C (40 pts) treated with interferon alpha we examined the cholesterol, HDL, LDL-lipoproteins and TG levels in blood serum at the beginning of therapy and in the sixth month. Changes of lipids values at the beginning and in the sixth month of therapy were assessed in respect to: necro-inflammatory changes of the liver in histopathological examination, degrees of fibrosis, obesity, loss of the weight during IFN therapy, response to treatment, type of hepatotropic viruses (HBV, HCV), sex and age. RESULTS AND CONCLUSIONS: During sixth month of interferon therapy there was significant decrease of total cholesterol level (before treatment 4.1 +/- 1.0, after treatment 3.8 +/- 0.9, p < 0.05) and HDL-lipoproteins level (before treatment 1.3 +/- 0.35, after treatment 1.1 +/- 0.35, p < 0.05). Increase of TG level was not statistically significant. The necro-inflammatory changes in the liver correlated with the values of TG level. Low activity of hepatic inflammation correlated with the increased TG level at sixth month of therapy. There was not observed effect of any other factors on the lipid metabolism.
